The cyclotron is a pretty nice rocket for the price! If you have worked with LOC kits before you'll have no issues with it. If you are looking for this to be your first Mid Power rocket you might find the instructions to be sparse but they are more than effective if you follow them closely. You will need 5/10 minute epoxy for this build - one key difference from other low/mid power kits from HobbyLinc.
I built this as stock and according to the instructions with the following exceptions: I chose to use Rail Buttons instead of a launch lug (the instructions for the launch lug, however are easy to follow for the first timer) and I added in a cheap motor retention using well nuts and mirror clips from the hardware store (about $2 in hardware) since my field requires motor retention rather than friction as the instructions suggest.
You can certainly spend more money and add more weight adding in a different recovery system, a more expensive motor retention device or fiberglassing the tubes. However, none of that needs to be done and the amount of time, money and effort you choose to spend on this is completely up to you. As packaged, it is a really fun and simple build that can be completed in a weekend with time to spare but it can also become a complex project if you are looking for that kind of challenge.
The body tubes have some small spirals but they are nothing to lose your mind over - a shot of primer and coat of paint and you can't really see them. The tube fins make for easy finishing as well since there is no balsa/plywood to fill in. This rocket is a fantastic canvas to paint on - the tubes offer some fun options if you are artistically inclined (I always liked red on the inside of the tubes for a cool effect). If you are not artistically inclined, a coat of paint and you're good to go!
In the end a unique rocket that is easy to build and is a blast to fly on F, G and H motors. In the end having fun is what a hobby is all about, right?
